A few essential genetic loci distinguish Penstemon species with flowers adapted to pollination by bees or hummingbirds Open
In the formation of species, adaptation by natural selection generates distinct combinations of traits that function well together. The maintenance of adaptive trait combinations in the face of gene flow depends on the strength and nature …

Complex cross-incompatibility in morning glories is consistent with a role for mating system in plant speciation Open
Reproductive isolation between selfing and outcrossing species can arise through diverse mechanisms, some of which are directly associated with differences in mating system. We dissected cross-incompatibility between the highly selfing mor…

Expression inheritance and constraints on cis- and trans-regulatory mutations underlying lotus color variation Open
Both cis- and trans-regulatory mutations drive changes in gene expression that underpin plant phenotypic evolution. However, how and why these two major types of regulatory mutations arise in different genes and how gene expression is inhe…

Modularity and selection of nectar traits in the evolution of the selfing syndrome in <i>Ipomoea lacunosa</i> (Convolvulaceae) Open
Summary Although the evolution of the selfing syndrome often involves reductions in floral size, pollen and nectar, few studies of selfing syndrome divergence have examined nectar. We investigate whether nectar traits have evolved independ…

GENETIC ARCHITECTURE OF DIVERGENCE: THE SELFING SYNDROME IN<i>IPOMOEA LACUNOSA</i> Open
Premise of the study Highly selfing plant species frequently display a distinctive suite of traits termed the “selfing syndrome.” This study tests the hypothesis that these traits are grouped into correlated evolutionary modules and determ…

Morning glory species co-occurrence is associated with asymmetrically decreased and cascading reproductive isolation Open
Hybridization between species can affect the strength of the reproductive barriers that separate those species. Two extensions of this effect are (1) the expectation that asymmetric hybridization or gene flow will have asymmetric effects o…

Selection favors loss of floral pigmentation in a highly selfing morning glory Open
A common evolutionary trend in highly selfing plants is the evolution of the “selfing syndrome”, in which traits associated with pollinator attraction are lost or greatly reduced. Limited information is available on whether these trait red…

The genome of a cave plant, <i>Primulina huaijiensis</i>, provides insights into adaptation to limestone karst habitats Open
Summary Although whole genome duplication (WGD) has been suggested to facilitate adaptive evolution and diversification, the role of specific WGD events in promoting diversification and adaptation in angiosperms remains poorly understood. …
